Title: Current drive circuit
Inventor: ONO AKIHIKO
IPC: G11B5/02
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To obtain a current driver circuit capable of smoothly controlling the output current waveform while securing the switching speed. SOLUTION: In accordance with two input signals Vi1, Vi2, a load circuit 14 consisting of the inductive load is driven by first and second driving circuits 11, 12. First and second damping control signals SP1, SP2 are produced based on the input signals Vi1, Vi2. The first and second damping control signals SP1, SP2 become the L-level with the timing generating an overshoot at the time of switching operation of the current drive circuit 10. Thus, the current is supplied to output terminals OUT1, OUT2 from damping circuits 23, 24, and the current flowing in the load circuit 14 is restricted, thereby the overshoot of the output current is reduced.

Title: Alarm stopping device for alarm clock
Inventor: KOBAYASHI MASAYUKI
IPC: G04B23/03
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To surely operate a switch even by pressing any part of an alarm stop button. SOLUTION: An alarm stop button 2 is fitted to the top plate part 1b of a frame body 1 so as to be capable of freely moving up and down. The alarm stop button has an expansible and contractible pantograph mechanism 4 having engaging parts 7b opposed to the lateral lower end parts of the alarm stop button 2, and this pantograph mechanism 4 is energized by an energizing means (switch 3) in the expanding direction. The switch 3 which is turned on/off interlocking with the expanding and contracting direction is provided below a lower link 6 forming the pantograph mechanism 4. Even when any part of the alarm stop button 2 is pushed, the switch 3 is surely operated by the pantograph mechanism 4 to stop the generation of alarm sound. Since the switch is surely operated even if the alarm stop button is obliquely pushed, one switch suffices for this.

Title: Automobile running controller of continuously variable transmission
Inventor: TERUI TOSHIYASU
IPC: B60W10/101
Filed: 1987-10-20
Abstract: PURPOSE:To avoid faulty transmission control by executing the primary control wherein a target transmission ratio is computed and a transmission means is driven at high speed before executing the secondary control wherein a control means compensates a difference between the primarily controlled transmission ratio and the actual transmission ratio to drive the transmission ratio at a lower speed according to the transmission information. CONSTITUTION:A primary control means 1 drives a target transmission ratio according to transmission control information 4, operates a driving means 6 at a higher driving speed set by a driving speed control means 5, and controls the transmission ratio of a continuously variable transmission gear via a speed changing means 7. Then, after the time is set on a timer means 3, a secondary control means 2 computes the actual transmission ratio using a both car speed 8 and an engine revolution speed 9, and controls the driving means 6 at a low driving speed set by the control means 5 to compensate the difference between the target transmission ratio and the other target transmission ratio given by the primary control. In such control, according to the information concerning a car speed 8, an engine revolution speed 9 and transient execution of the primary control 1, a control means 100 cuts off the secondary control 2 when the transmission ratio is within the range wherein a clutch is slipped. Thus a faulty transmission control can be avoided.

Title: Electric cooker
Inventor: TSUKADA SATORU
IPC: A47J27/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To control an electric pot or the like at a temperature close to that of actual hot water in a stable manner regardless of the influence exerted on a temperature sensing means. SOLUTION: Temperatures sensed by a temperature sensing means 13 do not always conform to that of actual hot water. For example, when water is boiled, the sensed temperature is higher than that of actual hot water by being influenced by the heat of a water heater 2, and when retaining heat, the sensed temperature is lower than that of actual hot water by being influenced the dissipation of heat. Hence, two temperature comparison means 14, 15 are provided in order to judge the temperatures sensed by the means 13, and the means 14, 15 are separately used in boiling and in heat retaining.  For example, in order to judge whether or not the temperature of actual hot water is 90 deg.C, in the means 14 for the use in boiling, temperatures sensed by the means 13 are compared with 94 deg.C, while in the means 15 for the use in heat retaining, temperatures sensed by the means 13 are compared with 85 deg.C.

Title: Method and device for drawing pipe
Inventor: OTA SHIGEO
IPC: B21D41/04
Filed: 1986-11-07
Abstract: PURPOSE:To eliminate a verticle wrinkle on the inside peripheral surface, and also, to release the residual internal stress of a pipe, by bringing the pipe to drawing by a die, and thereafter, ironing its inside periphery in a state that the outside periphery of the pipe is not constrained, at the time of detecting the pipe from the die. CONSTITUTION:A pipe P is pressed into a forming hole part 11 of a die 9 and brought to drawing to a prescribed shape. When drawing is ended, a knockout member 19 is allowed to abut on the end face of the pipe P by operating a knockout pin 20, and the pipe P is operated in the direction where it is detached from the forming hole part 11.

Title: Manufacture of laminated sheet
Inventor: TAKEMOTO MASAKAZU
IPC: B29C37/00
Filed: 1984-12-18
Abstract: PURPOSE:To prevent bubbles from remaining and a surface from being soiled, by blowing cold air to lower the temperature of the peripheral section of a laminate than that of the central section thereof in the early stage of molding when the laminate is pressed and molded under heating, and making the temperature of that peripheral section the same as or equal to that of that central section in the latter stage of the molding. CONSTITUTION:When a laminate is pressed and molded under heating, cold air is blown against the peripheral section of the laminate in the early stage of the molding at the temperature of 60-120 deg.C where the impregnated resin will be softened so that the temperature of part or all of the peripheral section of the laminate may be made lower than that of the central section by 2-50 deg.C. The term 'cold air' means air at about normal temperatures or lower than that. If, at the softening temperature of the resin, the temperature of the laminate is uniform or the peripheral temperature is higher than that of the remaining part, bubbles at the central section must pass through the melted resin for a long distance to the peripheral section of the laminate, but if the peripheral temperature is lower, the peripheral section is not melted, and is porous, so that the bubbles easily pass through the resin for a short distance to complete the passage without the flow of the resin. In the later stage of the molding, the temperature of the peripheral section of the laminate 2 is made the same as or higher than that of the central section.
